Nusii Proposals — proposal management integration

integrations

Nusii Proposals is a Claude Code skill that connects to Nusii Proposals via the Membrane CLI, enabling management of proposals, clients, templates, and users directly from the agent. It supports natural-language action discovery, running actions with JSON input parameters, and sending proxy requests straight to the Nusii API — with Membrane handling authentication and credential refresh transparently. The skill works with core entities: Proposal (with nested Section and Line Item), Client, and Template. Freelancers, agencies, and consultants can use it to automate their sales proposal workflow without dealing with API auth plumbing. A Membrane account (free tier supported) and network access are required.
